Application filed February 8,1907. Serial No. 356,320.

- Be it known that i., Eiinnii il.. Srimn, a citizen oi" the United States, residing` at Akron, in the county ot' Summit and bftate ol' Ohio, have invented certain new and useful improvements iii Conveyors, oi which the following is a speei'lication.

My invention relates to improvements in conveyors and is especially designed i'or use in conveying concrete in buckets for use iii the construction ol concrete structures.

The invention relates more particularly to an endless carrier-chain adapted to travel within an endless steel cliaii'i-guide-hox, said chain lieiiig,- made up ola series oll carryingliiiks connected hy means olA a series ol' intei'- mediate coiiiiectiiig-links and the chain being adapted to lie moved h v means oll sprocketwlieels connected to suitalile gearino, prel'erahly secured to said eliain-triiide-liox at its The carrieri upwardly-iiieliiied portions.

c-liaiii .is provided at siiitiilile intervals with depending bucket-cairier-arnis pivotzillv-se'- cured to carrier-links and extending a longitudinal opening|` Buckets are secured to the c'iiri'ier-ariiis and the A,{iiide-hox ma)v he extended horizontally to cari)r the liiickets wherever desired wliile the. 'building or ot liersl ructure is iii the course oll ereetion. i\ siiitulile horizontal portion is suitalilv supported aliove the 'roiind near the `concrete-niiiter where t-lie liiickets iiiav lie lilled as desired.

'l`lie primary` oliiect ol' the invention is to "provide :i geiiei'allyiiiproved eoiiveyer ol' this class which will he exceediiigl),v simple iii const ructioii, cheap oln iiianiit'xictui'e, and ellicieiit iii use.

Willi these and other ends iii view, the invention consists iii the novel construction7 arraiitfeiiienland 'coiiiliinutioii ol' parts, liereiiialter descrilied, illustrated in the aceoiiipaiiving drawings, and particularly pointed oiit iii tlit` appended claims.

ltelerrincr to the accoiiipaii^ \'iiig drawings, 'loi-minou part. oll this speci'leatioii, Figure l is a rear view ot :in inclined upwardly-extendiner portion ot' the chain-gtiide-liox with 1 improved chain-driving"Y mechanism.

The rollers 14, are adapted to engage with .the sides ol' the guide-hok to reduce Ylrietioii in making lateral or horizontal turns, as well :is in keepingr the chain in proper position within the guide-box. i The convuyerehain is also provided with l, i

vertical pivotal-connections eonsisting 0ilugs 17, formed at the end oi the connecting- .inks t), opposite the lugs 11., :incita-king over a lug 1S, formed at one end of the carryingllanges 7, i'oi the purpose ot" links 8. A horizontal 'through sui lugl.
